    摘要： A color space correction circuit in a display apparatus comprises: means for holding optimal R, G and B correction values at chromaticity coordinate points corresponding to a white, primary colors and complementary colors, respectively, in a color reproduction region of a display on a chromaticity diagram; means for connecting the respective chromaticity coordinate points corresponding to the primary colors and the complementary colors to the chromaticity coordinate point corresponding to the white in the color reproduction region of the display on the chromaticity diagram, thereby dividing the color reproduction region of the display into a plurality of areas and judging to which area the chromaticity coordinate points corresponding to input signals belong; and means for correcting R, G and B values for the input signals based on optimal R, G and B correction values corresponding to the chromaticity coordinate points that correspond to three vertexes of the area to which the chromaticity coordinate points corresponding to the input signals are judged to belong, and based on the R, G and B values for the input signals.

    摘要： The invention provides an organic LED display device of the digital drive type which has a display panel comprising a plurality of pixels 51. Each of the pixels 51 comprises an organic EL element 50, a drive transistor TR2 for effecting or interrupting the passage of current through the EL element 50 in response to the input of an on/off control signal, a write transistor TR1 to be brought into conduction upon receiving scanning voltage applied thereto from a scanning driver, a capacitance element C to be supplied with data voltage from a data driver by the write transistor TR1 conducting, and a comparator 9 for comparing a predetermined ramp voltage with the output voltage of the capacitance element C and supplying the result of comparison to the drive transistor TR2 as the on/off control signal.
